Sharp/NEC 8M B80Ax1U Control Spec

Summary

Projector control spec for the Sharp/NEC 8M B80Ax1U projector, covering the binary control protocol documented in the vendor Projector Control Command Reference Manual (BDT140013 Rev 7.1). The device supports both TCP/IP (port 7142) and RS-232C serial control with identical binary command framing (commands begin with a command header byte, end with a checksum byte).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # all listed as supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source lists "Full duplex" communication mode but no explicit flow_control field
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON / POWER OFF commands (015, 016)
  - queryable       # inferred: numerous query commands returning state
  - levelable       # inferred: PICTURE ADJUST, VOLUME ADJUST, OTHER ADJUST commands
  - routable        # inferred: INPUT SW CHANGE command (018)

# Error bitmap (command 009) reports interlock switch open, cover errors, foreign matter sensor, lens-not-installed - these are status indicators, not documented interlock sequences.

Notes

• All command/response frames use the same structure: header <ID1> <ID2> LEN <DATA...> <CKS>. ID1 is the projector control ID, ID2 is the model code (model-specific, not stated in this source).
• Checksum (CKS): sum of all preceding bytes, low-order 8 bits. Example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.
• Error responses use header byte AXh (where X matches command group) and carry ERR1/ERR2 codes (see source section 2.4 for full error code list, codes 00h-03h × 00h-0Fh).
• Source documents a generic command set covering multiple Sharp/NEC projector models; model-specific value tables (input terminal values, aspect values, eco mode values, base model types, sub input values) live in an Appendix "Supplementary Information by Command" that is not present in the extracted source text. Parameter enum values for those actions reference the appendix.
• Two-lamp variants (Lamp 2 selectors in commands 037-4) only apply to two-lamp projector models.
• Source: BDT140013 Revision 7.1, Projector Control Command Reference Manual.

Spec ready. 53 actions, all payloads verbatim. UNRESOLVED markers on appendix-dependent enums, model/control IDs, firmware version.

## Known Gaps

```yaml
- "specific firmware version compatibility not stated in source"
- "model code (ID2) value for this specific model not stated in source"
- "control ID (ID1) default value not stated in source"
- "source lists \"Full duplex\" communication mode but no explicit flow_control field"
- "full enum value lists for several feedbacks (eco mode, edge blending) reference appendix not present in extracted text"
- "no unsolicited notification events documented in source."
- "no multi-step command sequences described explicitly in source."
- "no explicit power-on sequencing requirements or interlock hardware procedures beyond command lockouts."
- "model code (ID2) value for 8M B80Ax1U not stated in source"
- "control ID (ID1) default not stated in source"
- "Appendix 'Supplementary Information by Command' not in extracted text — input terminal, aspect, eco mode, base model type, and sub input enum values missing"
- "firmware version compatibility not stated"
- "TCP keepalive / connection timeout behavior not stated"
- "command inter-command timing / minimum interval not stated"
- "flow_control explicitly stated only as 'Full duplex' communication mode; not mapped to standard flow_control enum"
```
